Hey if you do upgrade and want to sell the source turbo let me know. I run the small one right now but I either need another small one or a big one to make enough medicine for myself.Looking at what specialty equipment is affordable to the average person. Specifically, evaporators/distillers.
I have seen several Short Path Still options that seem very reasonably priced if I ever graduate to distillates. First off, I got to get extraction down so I consistently get same results.
I started out with extractions the hillbilly way. Soak flower, and then evaporate solvent to atmosphere in a double boiler on the stove. I progressed to a Source Turbo with little research. Now I furthered my research of other methods of solvent recovery. Rotary Evaporation and Wiped Film. Wiped film looks out of the question because of cost and complexity. But I discovered Rotary Evaporation is not all that expensive. Less than or equal to what I paid for the Source Turbo. That is if any of what I found is even worth buying.
With that said, I have a couple of questions. I only need a small scale unit. This is for personal use. So average batch of oil would likely start with 4oz flower. Or is that too small of scale to utilize a rotovap?
1) Is a rotary evaporator more efficient than the Source Turbo in terms of solvent removal? Its function and design alone tells me it would be far superior. I am satisfied with theamount of solvent Source Turbo recovers, but does a rotovap leave less residual solvent in finished oil?
2) If so, what kind of quality would I be looking at for a rotovap around $700CAD?
Any suggestions on a quality but affordable rotovap?
Thanks
No, 4 oz is not too small, but it will take a while to get your $ value back with such small amounts.I started out with extractions the hillbilly way.

It would take big balls to drive a few pounds across several states but if ya ever come up this way we could process a metric shit ton for you over a weekend.Got good use out that turbo turned me onto alcohol extraction- I passed it on to Amy as I felt she needed the meds worst than me - ready for that rotovap myself just haven’t pulled the trigger , and yep all about quality I’ll never get my money back as we just produce for family - but I sure like having quality product .
Ima be in Michigan this weekend! SW Michigan prolly 4/5 hrs from ya thanx but yeah my balls not that big I’m allergic to plexiglassIt would take big balls to drive a few pounds across several states but if ya ever come up this way we could process a metric shit ton for you over a weekend.
Ya, I can see and appreciate the off-set in use between the two. Takes a shit-ton of rotovap'in to get enough oil to distill. Problem is sourcing herb. I dont grow so I have to purchase. So that is the problem for me. That is what sucks. I can get bud at decent prices, but under the table and quality sometimes questionable. This is all personal use and I want to be as legit as possible. Cannabis being legal still has hurdles.BTW In have a short path as well. Rotovap is used 5X or more - if you only get one make it the rotovap.
Is a chiller absolutely necessary? Could I just run cold tap water thru the condenser? The water here even in the summer is very cold out of the tap. It wouldnt take that big of a stream. What is the ideal water temp for circulating the condenser?I don’t think you can get it done for 1000. A proper chiller will cost that much alone.

Thanks for the reply but I have a Source Turbo already. I am sure the Source works as well as that or better. I want to step-up a notch and get the real deal.Isomizer by Gold who wrote cannabis alchemy.

Ok not sure where to start. You have obviously given this some thought and research but I think you are missing some data in your search.
First, all these things need to be sized correctly to work together. I can’t comment on the pump without seeing the rotovap. Got a link?
Yes you will need either a cold trap or you will damage your pump eventually. There are other vacuum pumps that use water that do not require a cold trap. But again the pump needs to be sized to the rotovap so we need to start there.
There is really no point to upgrading to a rotovap if you do not use a chiller. You want your coils to be -20C to 0C max which equates to a 35C bath. If you run cold tap water (maybe 15C?) your bath has to go up to 50C minimum which is about what you get with your source turbo. Since you are dealing with small quantities there is no real incentive to upgrade.
Vacuum controller should be another $1000 us if you want a proper setup. I cannot comment on the one you linked, except to say turning on and off the pump is a hacky solution and I would rather buy the right pump that can be run full on all the time and eliminate the controller if it is not in the budget.
Really, for the price range you are in you already have the right product.
I’ll start you off hereThanks very much for the reply Moe! That definitely adds some insight. But I am not discouraged yet. LOL
So I definitely want a chiller? Please excuse my ignorance. But could you please explain the differential between coil temp and bath temp? Am I correct to assume Bath = the temp of water circulated inside the condenser? Speaking of the condenser, why are some orientated vertical and some near horizontal?
I was hoping to get a rotovap with a smaller capacity. That seems to be 2L. A 1L evaporating flask would be more practical for me, but havent seen any that small. Average batch to process would be 0.25-0.5 LB of flower. Takes way too long in the Source Turbo. Plus, I like absolute control. Cant control heat or vacuum with the ST.
An example of wanting control:
I wasnt sure I was decarbing proper in the oven because I could never get a buzz from edibles. So when I came across the Ardent Nova Decarboxylator, I grabbed one. Threw 1oz of premium flower in it and ran it thru it's cycle. Bud turned brownish and aroma changed. There was some condensation on lid when finished and bud was still somewhat hydrated. Ground up 3g and put in a yogurt smoothie and had no effect. Threw the Ardent in the corner. I dont trust it one bit. It left me wondering if my tolerance is really high, or the Ardent is bunk. To error on the safe side, I wont use it anymore. Back to the oven.
VACUUM PUMP and CONTROLLER
I was hoping to pick people's brains here prior to buying a vacuum pump. All of the components for that matter. But I didnt want to clutter forum with so many questions, then piss people off to the point nobody relies. So I went ahead and bought a pump that I thought would be suitable to 'ghetto' an operational rig together. I assumed the pump, being a 2 stage and 1/2HP, would be more than adequate for a small rotovap. I also assumed I would need a cold/vapor trap. I didnt think to look for that feature on the pump.
I seen some vacuum systems with a tank as well. Is there any advantage? Would that reduce the frequency of the pump needing to be switching on and off during evaporation? I do have a compressor tank I could incorporate if so.
As you stated, the vacuum controller I linked to is pretty basic. That is something I can upgrade in the future. I realize it isnt optimal, but it should get me in the door and do the job. If and when I do decide to upgrade the controller, what features should I look for?
Again thanks for the reply.
No the bath is the the water bath that the sourced vessel sits in. So this is your start point.So I definitely want a chiller? Please excuse my ignorance.

For all the reasons stated above, and the fact that this is a balancing act between molecular forces, you need everything sized to match in the whole system. Buying things piecemeal is fine, as long as it is part of a well designed system. Because you don't have the rotovap yet, that would concern me.VACUUM PUMP and CONTROLLER

Could you post a link to this? Can you explain exactly what is it? I have seen this several times. But not sure exactly what it does. It serves as a vacuum pump and chiller?View attachment 1262762
Relatively cheap, can easily get down to well under 40 Torr, and no need for cold trap.
You can use that, run it full bore all the time and use a bleed valve at the receiving flask to manually set vacuum - cheap and somewhat effective.
I show it in use in the video I linked 2 times.Could you post a link to this? Can you explain exactly what is it? I have seen this several times. But not sure exactly what it does. It serves as a vacuum pump and chiller?
